Configuring an Interface to Proactively Send Prestandard MSTP Messages -
CLI Version
By default, interfaces on a device running MST send prestandard, rather than standard, MSTP messages after
they receive a prestandard MSTP message from another interface. You can configure the interface to proactively
send prestandard MSTP messages. That is, the specified interface would not have to wait to receive a
prestandard MSTP message; the interface with this configuration always sends prestandard MSTP messages.
